ROC analysis is a standard method for estimating and comparing diagnostic tests’ accuracies when the gold standard is binary. However, there are many situations when the gold standard is not binary. In these situations, traditional ROC methods applied have lead to biased and uninformative outcomes. This article introduces nonbinROC, software for R that implements nonparametric estimators propos...

Some 10 years ago, Canadian health care organizations came under extreme pressure to cut costs as a result of a $4 billion cut in federal transfer payments to the provinces (Merrifield, 2003). This led to facility closures, cutting of beds on hospital wards, and moves to outpatient and community-based care. Health care employees felt the impact as well, with health professionals reporting loss ...

Female expatriates have been found to have better work adjustment and interaction adjustment than male expatriates, despite the additional challenges faced by women on foreign assignments. This paper considers three possible explanations for this finding: higher self-transcendence, experience in domestic contexts; and female work styles. Research propositions are proposed for future empirical t...

Flow tracking is an integral aspect of many network-related applications, including intrusion detection, network administration, per-flow billing, and network engineering. While some applications do not require precise tracking of every packet or flow and successfully employ statistical sampling or approximations to achieve an acceptable level of accuracy, many others, especially in the securit...

The paper presents a global Finite Element Method model developed to understand and quantify the complex phenomena of energetic transfer and overpressure taking place within a transformer vessel during and after a short-circuit. The goal of the model is to design an efficient system able to protect Power Transformers against explosion and resulting oil fire. The model presentation and compariso...

The concept of a phasor synchronized with the power system was introduced in the 1980s and standardized for the first time with the standard IEEE 1344. That measurement concept was further developed in the current synchrophasor standard, IEEE C37.118 that was completed in 2005. It is currently undergoing revision to fully define the measurement in all conditions including dynamic changes in the...
